Method for drawing morphology of fish eggs and larvae

Abstract

The invention relates to a method for drawing morphology of fish eggs and larvae. The method performs developmental stage determination and preliminary species identification on the fish eggs and larvae based on a biological anatomical lens. The morphological characteristics of the fish eggs and larvae are subjected to shooting processing by a high-resolution microscopy, then pictures of various parts of the fish eggs and larvae are taken and Photoshop software is used for picture overlay processing, and finally the pictures with all the clear morphological characteristics of the fish eggs andlarvae are exported; and then the photographed fish eggs and larvae are subjected to molecular biological treatment to determine the species, then the pictures are matched with the species, the pictures are copied and processed on vegetable parchment by printing the pictures and placed into a scanner for scan processing, and finally the morphological characteristics and morphological developmentpatterns of the fish eggs and larvae are obtained. The method overcomes the deficiency that the morphological characteristics of the fish eggs and larvae need to be drawn by experts engaged in drawingand the related fields of fish features in the past, and has the advantages of being fast, accurate and efficient.

Description

technical field [0001] The invention relates to the field of fishery, in particular to a method for drawing the shape of fish eggs and juvenile fish. Background technique [0002] The identification of fish species at early developmental stages is the basis for fish early life history studies. The traditional identification methods of early fish resource species are mainly based on the early individual morphological characteristics, and use the differences in various countable traits, quantifiable traits and descriptive traits in the early development stages of different species to distinguish different species. From the perspective of the history of larvae research, the research on larvae and juveniles in foreign countries was carried out very early, even dating back to the 1880s and 1990s, which mainly focused on the research of fish spawning habits and embryonic development. Developed countries such as Europe, America, and Japan have accumulated a large number of scienti...

Problems solved by technology

This method overcomes the disadvantage of strong subjectivity in morphological identification, and has the advantages of high sensitivity and good repeatability. It has been widely used in the identification of early fish resource species. Identification, by observing the individual morphological characteristics of fish eggs and larvae and drawing developmental morphological maps, the previous morphological characteristics drawing often required long-term drawing and experts in fish characteristics-related fields to draw early fish resources The morphological feature map, the process is time-consuming and labor-intensive and the efficiency is low
